MACHINE FOR MAKING BRUSHES.

SPECIFICATION forming part of Letters Patent No. 356,330, dated January 18, 1887.

Application filed May 22, 1884.

To all whom it may concern:

Be it known that we, LOFTUS E. Peron and CHARLES L. SHERMAN, of the town of New Lots, county of Kings, and State of New York, have invented certain new and useful Improvements in Machines for Making Brushes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Our invention has relation to machines employed in the manufacture of brushes, the object of our invention being to produce a simple, cheap, easilyoperating, and effective machine by use of which the bristles may be rapidly, conveniently,and accurately applied upon the brusl1head, saving much labor and time over the methods heretofore ordinarily adopted,whicli required skilled labor, and ren dering it practicable for the work to be performed by any ordinary person.

To accomplish this our improvements involve certain novel and useful peculiarities of construction and relative arrangements or combinations of parts, all of which will be herein first fully described, and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan or top View of a machine constructed and arranged for operation in accordance with our invention andiuvolving the principles thereof, the jaws being shown in openposition ready to receive the brush-head and the arranged bristles to be applied thereon. Fig. 2 is a sectional elevation upon a plane passing through liner 0: of Fig. 1, and Fig. 3 is a similar View upon a plane passing through line 9/ Fig. 4. represents a side elevation of the bunch of bristles arranged in their holder and the brushhead detached therefrom; and Fig. 5 is a crosssection showing the bunch upon the head. Fig. 6 is a cross-section of the brush-head, showing the bunch of bristles applied thereon, the bristle-holder of Figs. 5 and 4t omitted, and a metallic band placed over the bristles ready to be crowded down to place, so as to finally secure them on the head. Fig. 7 is a similar cross-section showing the metallic band forced down to its final seat. Fig. 8 is a perspective View of the machine turned sidewise, one of Serial No. 132,364. (MotleL) the levers N being advanced and the other retraotcd.

In all the figures like letters of reference,-

wherever they occur, indicate corresponding parts.

A represents a brush-head, which in this case is shown to be flat, like the heads of broad brushes, and provided with a ledge, a, against which the ends of the bristles may abut.

B is the tuft of bristles to be applied upon the head, said tuft being arranged in a suitable holder, G, whereby it is divided .and spread at the bottom, as in Figs. 5, 6, and 7, so that it may be easily located over the projecting part 'b of head A. The tuft, or the two parts thereof, are wider than projection 12, so that they may be carried around the ends of the projection to complete the brush at the sides and ends. The bristles being placed in the holder, which maybe of any suitable pattern, their lower extremities are dipped in cement and made ready to be applied to the brush-head.

The bristles may be disposed'in the holders by any ordinary labor.

\Ve make no claim herein on the holder.

The purpose of the machine is to facilitate the application of the bristles to the head.

D D represent two main side plates or jaws, arranged to approach or recede from each other through the action or movement of suitable appliances-as the levers E Ewhich are operated by a treadle, F, connected with the levers through the medium of arod, G, bar H, and links I I.

K and L are springs by which the jaws D D are automatically returned to their opened position as soon as they are released.

M M are other jaws, made movable through the medium of hand' levers N N, connected therewith and acted upon by springs O O, by

which the jaws are normally held. in open position.

P P are adjustable guides arranged to be set at any distance from each other, so as to take in any desired length of brush-head; and l? P are guides set so as to accommodate the thickness of the brush -head, and hold the head in proper relation with the parts of the machine.

Upon the bed-plate Q are small detents c c,

calculated to arrest the brush head at the proper point, and to prevent it dropping through the central opening.

D D are auxiliaryjaws' mounted upon the jaws D D,and made movable therewith or independently thereof, as occasion may require.

The brush-head is dropped in upon the dc tents c c and between the guides I? P, and the bunch of bristles in the holder is placed over the head, as in Fig. 5. The trcadle is then depressed, bringing the jaws or plates D D and D D to bear against the bristles and press them firmly on the head The end jaws, M, are then made to approach the bristles by the handles N N, said jaws being curved on their bearing-faces, so as to bend the bristles around the end of the projection b. The jaws D are slotted, as at (I, to permit thejaws M to travel 'up to place, the jaws M being provided with narrow lateral projections, as (1 dflwhieh move in the slots (7. \Vhen the brush isthus clamped, the bristleholder G rests above the jaws D D, which are mounted so that they may move independently of jaws D D. Two levers or cams, R R, connected with jaws D D, and bearing against studs 9 g, which are connected with jaws DD,conipeljaws D and D to move together when the levers are in the position indicated in Fig. 1. The holder 0 is then withdrawn and the metallic band f made to take its place, being crowded down to thejaws D. Then by swinging the levers R R back with the hand the studs 9 g are released and the jaws D D are instantly retracted by retracting-springs c 6, when the metallic band is further crowded down to thejaws D, holding the bristles in place. The treadleis then released, permitting the springs K and L to act so as to retract jaws D D, which in turn release the jaws M M, the latter having been clamped between D D, and the brush with the band may be removed from the machine, after which the band is crowded down to its final position, ready to be tacked in place. As the jaws D D are opened the levers It R are brought against abutments-yg' upon the bcd-plate, which auto matically turn said levers so that they will properly engage with the studs 9 g. The ma chine is then in readiness to receive another brush.

It will be observed that by use of the ma chine the bristles are quickly and accurately located upon the head in proper position to be finally secured, and the final tacking of the band f in place may be easily accomplished by any ordinary workman. The band is preferably first perforated at suitable intervals to aid in properly distributing the tacks which assist in securing the bristles upon the projections 7). Some tacks also enter the ledge a, so that the whole brush is firmly bound together.

The machine is easily operated, and in practice is found to admirably answer the purpose or object of the invention, as previously set forth.

In the representation ofour machi ne we have shown a treadle for operating the side or main jaws and handles for operating the end jaws.

Having now fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a brush-making machine, the combination, wilh the main jaws, of the auxiliaryjaws mounted thereon and made movable independently thereof, and the cam-levers and springs for operating said auxiliary jaws, substantially as and for the purposes set forth.

2. In a machine for making brushes,having detents forsustaining the brnsh-head, the combination, with the movable main jaws for clamping the. bristles upon the sides of the brush-head, of the operating-levers connected with the treadle, and the retracting-springs, applied and arranged substantially as shown and described.

3. In a machine of the character herein set forth, the main jaws, slotted, as explained, in combination with the end jaws provided with lateral projections arranged to enter the slots in the main jaws, substantially as shown and described.

4c. The auxiliary jaws mounted upon the main jaws, the cams or levers connected with the main j aws,and the abutments applied upon the bed-plate, all combined and arranged for operation substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our hands in the presence of two witnesses.
